Question

通过使用fabric-sdk-java客户端，我尝试使用 docker images Windows 7 中本地Hyperledger fabric V1.0 network设置的同级中调用安装和实例化的链代码>。我可以调用和查询对等链 peer0.org1.example.com 的链代码，但是当我尝试向对等 peer0.org2.example.com 时strong>收到以下错误

查看 docker-compose.yaml 端口映射就像

peer0.org1.example.com  
    ports:
      - 7051:7051
      - 7053:7053

peer0.org2.example.com    
        ports:
      - 8051:7051
      - 8053:7053

它仅适用于端口与tcp端口相同的端口（ 7051 ）但在端口 8051 的端口上遇到上述错误。为什么呢？

Answer 1

请澄清这个问题。在8051：7051表示法中，8051是＆＃34;外部＆＃34;可达端口和7051是docker镜像内的匹配端口。此外，＆＃34; UNAVAILABLE：频道＆＃34;错误似乎表明你在同行已经加入的结构通道名称中有一个拼写错误，请仔细检查？。

使用fabric-client-sdk，无法对多个对等方进行grpc调用
